The unit is adequate for general readings of waverforms in audio testing and automotive. The probes are alright, but I prefer my insulated 400MHz probes that are already in my kit. At times I would get erroneous readings that had me chasing my tail, but pulling the probes and going into the menu for a baseline calibration resolved that issue. The screen is nice and the touch is very responsive. Using the device in X-Y mode with my curve tracer setup was perfect. It's important that you get into the menu and adjust attenuation to be the same as what setting your probe is set at per channel. Used it today for repair of a Pioneer SX-1980 and honestly it paid for itself with this one job. Overall I'm very impressed with this unit and makes a fantastic addition to both my portable kit and the bench.
